You have a large balloon you want to fill, but you have very little helium left. You blow up the balloon with air first, which has nitrogen at 0.700 atm, oxygen at 0.235 atm, and other gases at 0.017 atm. If the balloon has a final pressure of 1.150 atm, what is the pressure of the helium you added after the air?
